Behind copper's record 2025 rally: Tariffs, supply hit, AI demand, Pg15

Key Highlights:

• Copper prices reached a record high in December 2025, exceeding $12,000 per tonne on the London Metal Exchange (LME).
• The metal's price surged over 35% in 2025, marking the largest annual increase since 2009.
• US President Donald Trump's 50% tariff on semi-finished copper imports in August 2025 led to stockpiling by US buyers.
• Supply disruptions in major copper mines in Indonesia, Chile, and the Democratic Republic of Congo have tightened global supply.
• Growing demand from artificial intelligence (AI), data centers, and the transition to clean mobility are driving copper demand.

Detailed Insights:

• The rise in copper prices is generally seen as an indicator of economic health, but the recent surge has occurred during steady, but not strong, global economic growth.
• The anticipation of tariffs on refined copper has further incentivized US buyers to build up copper reserves in warehouses, creating arbitrage opportunities in the market.
• Disruptions at major copper mines have coincided with increased demand from the expansion of AI and the construction of data centers, which require significant amounts of copper.
• The transition to electric vehicles, which use more than twice the amount of copper compared to conventional cars, is also contributing to the rising demand.
• A weakening US dollar, driven by expectations of interest rate cuts by the US Federal Reserve, has added upward pressure on copper prices, as copper is priced in US dollars.

Key Concepts Involved:

• Arbitrage: The simultaneous purchase and sale of an asset in different markets to profit from a price difference.
• Tariff: A tax or duty imposed on goods when they are transported across international borders.
• LME (London Metal Exchange): A futures and options exchange dealing in base metals.
